I think she should be seen by the Vet, just no way to tell
I completely agree with Margot. There's just no way to tell what the problem could be without having her examined by a vet and since she is a senior dog, something that might be minor in a young dog could quickly become serious if left untreated. Please keep us up to date on how she is.
